From the zlib.h documentation of deflateInit2():

  windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
determines the window size.  deflate() will then generate raw deflate data
with no zlib header or trailer, and will not compute a check value.

  windowBits can also be greater than 15 for optional gzip encoding.  Add
16 to windowBits to write a simple gzip header and trailer around the
compressed data instead of a zlib wrapper.
